ALBERT G. SCHERER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE EXCEL SIORSTEEL FURNACE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

HOT-AIR DISTRIBUTER FOR FURNACES.

Specification of Letters Patent.

Patented May 1, 1917.

Application filed November 15, 1913. Serial No. 801,120.

To all whom it may concern:

Be it known that I, ALBERT G. Sorrnnnn, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented a certain new and useful Hot-Air Distributer for Furnaces,of which the following is a specification.

It is generally known that with that variety of furnaces in which theheated air is conducted from the furnace to the portion of the premiseswhere it is desired by leads of hot air conduit, it often happens thatcertain of the leads take a great deal larger proportion of the hot airthan is necessary or desirable, while other leads do not get asufiicient quantity. This is occasioned by the fact that some of theleads are larger than others, some are more direct, some are shorter,and some both more direct and shorter. The structural features andconditions of the premises to be heated have to be accepted as they arefound, and while the employment of various sized leads will affordsufiicient conduit space to get the necessary amount of hot air to theparticular size room to properly heat it, the proportion of air which aparticular lead will take depends upon so many other conditions thansize or capacity, that it is found when the plant is installed that someof the leads are not delivering the amount of hot air which it isdesirable they should deliver.

My present invention has for its object the provision of facilitieswhich will permit of an adjustment so as to effect the desireddistribution of the hot air from the furnace to the various leads ofconduit with which it connects.

I attain the above object by the structure illustrated in theaccompanying drawing, in which:

Figure 1 is an elevation of a usual form of hot air furnace a portion ofthe top of the casing being broken away to show one of my distributingpartitions in place;

Fig. 2 is a view looking upward into the top of a furnace casing with mydistributor installed therein;

Fig. 3 is a view of one of the distributing partitions;

is e emental de a p n o the central connection for the distributing partitions;

Fig. 5 is a fragmental detail elevation of the structure shown in Fig.4; and

Fig. 6 is a fragmental detail similar to Fig. 4, showing how more thanone distributing plate may be assembled with a single bar 14.

Similar reference characters refer to similar parts throughout theseveral views.

1V hile my invention may be advantageously employed in any form of plantfor the distribution of hot air, I have illustrated the same inconnection with the usual form of hot air furnace, which, so far as Iknow, is by far the most widely distributed and best known apparatus ofthat kind.

The usual form of hot air furnace comprises a heater and radiatorportion surrounded by a casing, 1, as shown in Fig. 1. Air is admittedto the casing, and, after being heated by the heater and radiator, risesto the top or head, 2, of the casing from which it flows through thelead openings, 3, to the leads and through the premises.

I have shown a form of casing top or head, 2, which will facilitate theflow of the heated air. In this form of casing top or head the loweredge, 4, is cylindrical in form and of such size to fit the upper end ofthe body, 5, of the casing. Above the edge, 1, the casing top or head isgiven an upwardly and inwardly inclined direction or conical form, 6, inwhich portion the lead openings, 3, are provided. This arrangement givesthe leads an upward direction as they leave the furnace therebyfacilitating the easy flow of the light hot air from the furnace to theleads. Above the lead openings, 8, the walls of the casing top or headincline downwardly and inwardly to a central point 8, in the form of aninverted cone, 9. This form also facilitates the flow of the hot air tothe leads as it does away with the central dead space inwhich themovement of the hot air contiguous thereto would be given no directionand would be permitted to eddy and interfere with the flow of the restof the hot air.

Secured to and depending from the central point, 8, of the casing heador top, by means, of the bolt, 10, is the reel or pintle,

11, comprising the central hub, 12, the end plates, 13, and the bars,14, Which extend between the projections 15, provided upon theperipheries of the plates, 13.

Distributing plates, 16, are next provided, of a form to stand anddivide vertically a radius of the casing top or head. The inner verticaledge of the distributing plates is provided with a hook, 17, forengaging one of the bars, 14:, and the outer vertical edges thereof areprovided with the strap, 18, sliding in the bracket, 19, by means ofwhich strap 18 the outer edge of the distributing plates may be securedby riveting or otherwise, to the wall of the casing top or head in anydesired position. More than one distributing plate, 16, may be hookedupon or secured to a single bar, 14, so that the number of distributingplates that may be inserted in a casing top or head is much greater thanthe number of lead openings circumstances would require or the furnacesupply. With the above structure the relative amount of hot airdistributed to any lead is determined by the segment of the top allottedto its particular opening by the distributing plates. In actual practiceit is easy to adjust the distributing plates with a little experimentingso that each lead receives its proper proportion of hot air, and thelittle hall bedroom Way off in the end of the house receives heat asregularly and certainly as the living room which may be located directlyover the furnace.

Having described my invention what 1 claim as new and desire to secureby Letters Patent, is

A hot air distributer comprising a hot air casing, a heating elementwithin said casing, the top of said casing being provided with aperturesfor connection with hot air conduits, a reel located centrally withrespect to the top of said casing, a series of concentricallyand'consecutively disposed bars in said reel, plates, means upon theends of said plates for engaging said vertical bars, and means forsecuring the outer edges of said plates to the outer walls of the top ofsaid casing, said plates being adapted to divide only that space abovethe heating element into variable segments of suitable proportion to theapertures opening into'such respective segments.

In testimony whereof I afiix my signature in the presence of twowitnesses.
